具有龈下边缘的种植体冠的修复一直是一个挑战。如果做得准确，它会带来更好的治疗结果和预后。众所周知，由于不完全清除粘固剂，不正确的技术和不正确的操作会导致种植体周围病的高发病率。深基牙边缘很难辨认，如果牙槽深度大于3 mm，这些病例中的粘固剂去除就会变得复杂。无论使用哪种工具来清除多余的水泥，基台上的划痕和一些水泥残留物都会一直被注意到。因此，在口腔内植入假体前清除过量的粘固剂被认为是预防过量粘固剂引起的并发症的有效技术。本文介绍了一种用于基牙种植体冠粘接的座椅边通用技术，该技术具有较深的龈下边缘。这项技术试图最大限度地减少种植体周组织中多余的骨水泥。
Restoration of implant crowns with subgingival margins has always been a challenge. If done precisely it leads to better treatment outcomes and prognosis. An incorrect technique and improper execution of the luting procedure are known to cause a high incidence of peri-implant disease due to incomplete elimination of the luting agent. Deep subgingival abutment margins are difficult to recognize, and cement removal in these cases becomes complicated if the sulcus depth is greater than 3 mm. Irrespective of the type of instrument used to remove the excess cement, scratches on the abutment and some cement remnants are consistently noticed. Therefore elimination of excess luting agent before the prosthesis is inserted intraorally is considered an effective technique to prevent complications due to excess luting agent. This article presents a chairside universal technique for cementation of implant crowns on abutments with deep subgingival margins. This technique attempts to minimize the amount of excess cement in peri-implant tissue.
